　参考答案&解析：

　　1、D　因为the biggest ocean与compare是被动关系，所以要用过去分词。When compared with…=When the biggest ocean is compared with…=When we compare the biggest ocean with… 故答案为D。

　　2、C　首先，非谓语动词的否定式要将not, never等放在非谓语动词的前面，所以不能选D。其次，由于“没有完成”与“决定再呆两周”有先后关系，故用现在分词的完成式。故答案为C。

　　3、C　此题考查spend... (in) doing sth 句型。故答案为C。

　　4、C　因为be believed /thought /supposed /said /reported等后要接动词不定式，排除A和B;又因为the flu与cause是被动关系，所以要用不定式的被动式。The flu is believed to be caused by...=It is believed /People believe that the flu is caused by...故答案为C。

　　5、B　因为“发出香味”与“吸引游客”是同时发生的，且smell作为连系动词没有被动形式，所以答案选B。
